Patented Mar. 29, 1932 1 UNITED ST-ATEES PATENT! OFFICE CHARLES NORVIN RINEK, OF EASTON, PENNSYLVANIA METHOD F MAKING ROPE Application led J'une 1, 1931; Serial Ne. 541,510.

This invention relates to an improvement is suitably processed and fabricated to render in cordage, and niore'particularl to a novel it strong and durable While at the same time rope structure possessing strengt i, flexibility maintaining its iiexibility and increasing its and moisture resisting characteristics which tensile strength.V l f 6 contribute to the general durab-ility of the First, a cotton yarn or cord of the proper 55 rope and renders the same of Wide applicatwist is provided with a thorough coating of tion and service. the best quality pure Para gum. After the A primary object of the invention is to proyarn in the form of cords A is suitably coated Vide a rope having the foregoing ChaIaCteI- 0r impregnated, according t0 this step 0f 0 istics Which is made from cotton yarn or the method, the gum is permitted to dry and 60. other materials impregnated kWith rubber the coated cord is then Wound upon bobbins gum, the yarn thus impregnated being the l to be ready for fabricating into strands or foundation of the general rope structure readies, es shown in Fig, 1, Which includes several strands composed of The said cords A thus coated, are handled icords formed of the previously treated yarn. by a forming machine which includes passing 65 A further object of the invention iS t0 plO- the same through the thimble plate into a vide a rope structure which is relatively inyforming tube 2 which may be heated by a expensive, and susceptible of being made steam coil or its equivalent. The heat and from cotton fiber Which iS thoroughly Watelfriction will cause a certain amount of coheproofed thereby to adequately meet the USG sion to be imparted to the various yarn slivers 70 of a rope made from cotton yarn under concomprising the cord. The degree of yheat is ditions Which may require tS USS 111 Water carefully observed so that the cohesion is not Without impalring its tenSlle Strengtllsufficient to provide a solid mass `but will With the above and other obJects in view, cause the rubber t0 act as a. holder in keepthe invention consists in Jthe novel features ing the various yal-Hsin place, as Well as proof construction, combination, and arrangeviding a fiexibl'e Waterproof Covering, l ment of parts as will be hereinafter more The COI-ds A in passing through the formfiiiiy, described iiiiistieted iii che accom' inar tube 2 are made into readies or strands B Panylng d idWliigS and defined iii the ELP which are passed over the forming capstans im Pended CiamlS- 4 and then Wound upon the ready reels 5. 8

A Preferred end Practical eiiibcdimeiic 0f Thel readies from these reels may then be the invention isshown in the accompanying placed in a machine knownl as. a layer and drawings, in Which if a three-strand rope is to be made, three of Figsi and 2 die diagrammatic Views iiiiis these readies are used to produce the ordinary ti'iitiiig die iiiethcd Steps emliicyedthree-strand rope, as will be seen from Fig. 2. 85 Fig 3 iS d Peiepcctive View 0f, e mpc mede As the readies passfrom the reels 5 to and in accordance with the present invention. thrmlgh the forming dies 6, the heat genera/ Ropemade from Cott ber under Ordi' ed by the passage through suchdiesv constinary clrcumstimces Wlu not Stand the tutes a further stage for compressing the vain amount of abrasive, wear and tear as rope made from hard fiber such as manila and the like. However, owing to the abundant and readily available supply of cotton fiber, it is desirable to process the samey so that it may i5 be readily used as a substitute for rope made rious outside yarns of the strands or readies into their respective places and impartsl a finish to the rope C as a Whole. The rope is then passed over the finishing capstans 7.

' As will be observed from Fig. 3 the out- 95 from manila, abaca or other iibers. To that Side Yams ci cords 0f the Sii'iinds B are end the present invent-ion provides a rope bonded tcgeiiiei' Wiiiie the inside .Yarns 0i` lade ffoiin Cotton yarn, Such as the IS.. COIdS Of the Strand OI rea/dy are 1005 and fllee 13nd grade, which lay be expressly Spun and t0 HEX du@ t0 tll faCt that the heat il() WhlCll 6 laid exclusively for this purpose and which the strands or readies are subjected in pass- '100 ing through the tube 2 causes the outside yarns or cords to stick together.

From the foregoing it will be apparent that the present invention contemplates the use of a oord, fabricated from cotton yarn, the said cord being coated with Para gum, and as the cords are then passed through the forming tube and given the proper amount of twist, they are made into readies, which readies in turn are made into finished rope.

During the process of making t-he finished'- rope, the cords are first subjected tosuiicient heat to cause them to adhere to provide a relatively homogeneous outer coating: and, then the readies when formed into the tinishedrope are subjected to: further heat to additionally compress the strandsV or readies thereby to imparta finishing envelopeorgsur Y face to the completed structure.

Whilel it is, of course, to' be understood that the present invention has special; appli-- cation to the utilizationA of cotton yarn, it will, ofcourse, be understood. that. thei meth` od and the. product may be. equallyV efficient. with yarns havingcharacteristics similar to cotton.

Without further description it isthought that the features and advantages of the invention will be readily apparent to those skilled in theart, and itLwill ofcourseibe un'- derstood'tliat changes in the form, proper-"- tion and minordetails of'construction may be resorted to, without'departing from the spirit ofthe invention and scope of.' the appended claims.

I claim:

1'. A. method of forming rope from rubber coated; cords which consists: in simultaneously subjecting the coated cords to* pressure and heat while being assembled into' strands, and subsequently simultaneously subjecting the strands to' pressure and heat while being formed into rope.

2'. A method' of forming rope from rubber coated cords which consists in simultaneously subjecting the cords to pressure and heatl while being assembled intov strands whereby the outer yarns of the cords are adhesively connected and the internal yarns areV free to flex, and subsequently simultaneously subjecting the stra-nds to pressure and hea-t While being twisted into rope thereby to further compress the outsdeyarns andV impart a` fin.- ish to the-ropeas a whole.

In testimony whereof l hereuntoJ affix my signature.
